Rock Bursts in the Lake Superior Copper Mines, Keweenaw Point, Michigan (open access)

Rock Bursts in the Lake Superior Copper Mines, Keweenaw Point, Michigan

From Introduction: "The effect of rock pressure may be general and continuous disintegration and reduction in size of pillars of ore and rock left for the support of the workings, resulting in the collapse of hanging wall and the closing of stopes, drifts, and shafts, or the action may be sudden and violent and aside from seriously affecting the workings may present a real hazard to the operation of mines. The object in the preparation of this report is to add to the accumulated information and from the facts presented to make suggestions for protective measures to be taken when possible."

Abnormal grain growth in nickel-base heat-resistant alloys (open access)

Abnormal grain growth in nickel-base heat-resistant alloys

From Introduction: "The data included in this report for Nimonic 80A alloy, for instance, represent experiments carried out to help clarify a production problem of grain-size control in an alloy which has been extensively used. The general procedure of the investigation was to carry out controlled laboratory experiments on samples of bar stock to find conditions of heating and hot-working which resulted in abnormal grain growth."
